XF-45 on the first coin........some real neat die cracks happening on that piece. The second piece appears low AU/high XF, but I'm a little concerned with those marks which could indicate a harsh cleaning. Then again they could be die polish marks 'cause I know 'zip' about these pieces. Just goin' by my 'gut'.......
Do not think it is cleaned, pics on other specimens look the same? It has a very nice blue undertone which I cannot get with my photos.
A coin can be harshly and improperly cleaned at some point in time only to then start to tone there afterwards. But I agree with green18, the lines on the second coin indicate an improper cleaning at some point in this coins life.
